Abstract
MgO-C is based on magnesia and graphite as main raw materials plus the amount of binding agent by high-pressure molding, low temperature heat treatment made ??of refractory products. As China's economy continues to develop, along with the rapid development of the steel industry, refractory products in the development of the steel industry in the actor an important role, especially magnesium carbon refractories. MgO-C has excellent heat resistance, resistance to slag erosion resistance, slag permeability, thermal shock resistance, the nature of the structure is not easy peeling. So, is widely used in various fields, such as foreign ladle furnace, converter, tundish, the steel mouth, high power electric furnace wall and the hot parts of the refining furnace lining, etc. The converter design involving a total of MgO-C MT10A 28000 tons / year and converter MgO-C MT18A 20000 tons / year, an overview of the development situation Bricks, production processes, in the ladle slag line application and production plant design and planning, and prospected for its development prospects. Ensure that the design of the program to achieve scientific and feasible, economically reasonable technology, and continue the program optimization. Based on the above work, drawing a total annual production capacity of 48,000 tons magnesia carbon brick factory floor plan, shop floor plan and layout of the corresponding cross-sectional aspect total 12.
Key words: Magnesia-carbon bricks, Process, Magnesia carbon brick used in ladle, Refractory product
